Error when trying to use it in R via reticulate package

[GitHunter0]

Python modules are accessible in R via reticulate package. Unfortunately, it is not working for GEKKO, the formulas are not being recognized as such.

I am receiving these kind of error messages when trying to pass equations like in m$Equation(x1 + x2 == 7): Error in x1 + x2 : non-numeric argument to binary operator.

library(reticulate)
gekko <- reticulate::import("gekko")
m <- gekko$GEKKO(remote=TRUE) 
x1 = m$Var(value=1, lb=1, ub=5)
x2 = m$Var(value=5, lb=1, ub=5)
x3 = m$Var(value=5, lb=1, ub=5)
x4 = m$Var(value=1, lb=1, ub=5)
m$Equation(x1 + x2 == 7)
m$Equation(x1 * x2 * x3 * x4 >= 25)
m$Obj(x1 * x4 * (x1 + x2 + x3) + x3)  
m$solve(disp=TRUE)  

I would really like to use GEKKO in R, is there some tweak we can do to make that possible?

Thank you

This is an interesting question but I'm not very familiar with R. I posted the question on StackOverflow to see if there is any help from the R community. https://stackoverflow.com/questions/65291603/error-when-trying-to-use-python-gekko-in-r-via-reticulate-package

Hey @APMonitor, I appreciate the initiative, GEKKO is a great package and hopefully R users will be able to take advantage of it too.
